Good News: Perturbing the Peace
Prometheus perturbing Saturn's braided F Ring. This moon and others exist inside the "Roche Limit." It was once thought that this marked a demarcation line within which moons would be torn apart. Prometheus has one of the lowest densities of a solar system object, just 0.47 g/cm^3. That is less than 1/2 the density of liquid water. It is very odd that objects with less density than liquid should exist inside the Roche Limit, within which liquid objects are not supposed to exist.
Shepherd moons Prometheus and Pandora orbit on opposite sides of the Ring. These little moons could harbour something very dense within their cores. If Prometheus' 10^17 kg mass contained a 10^11 kg singularity, the moon would not be sucked up. Presence of a singularity would hold Prometheus together and also account for a magnetic field. The magnetic field of Prometheus has not been detected, but it will be.
Having followed this blog for nearly a year, you will be pleased to hear that a paper about GM=tc^3 has been accepted for publication by a major journal. This means a lot of work preparing illustrations and copyrights. It will lead to more publications, for other editors have been waiting for a major journal to take the lead. Publishing allows 49,000 subscribers to read a paper, far more than the audiences at conferences. Spreading a simple idea will not require so much travel.
On another subject, at the end of this month I hope to reveal a technology that will make human spaceflight safer, easier and far more comfortable.
